Thesis defense of Simone Mender

spectral and spatial analyses of gamma-ray data rely on the open-source Python package Gammapy. Due to this new approach from the gamma-ray community, the input data needs to be provided in a standardized [...] functions. In this thesis, a spectral analysis of the two TeV radio galaxy candidates TXS 0149+710 and 4C +39.12 observed by MAGIC is conducted. For this, standardized data is produced in an automated and [...] background models have to be included in the standardized data, which is not covered by AutoMAGIC yet. To address this challenge, 1441 observations of off data are processed with AutoMAGIC and the background shape …

Car-To-Cloud Communication Traffic Analysis Based on the Common Vehicle Information Model

achievable data rate making use of an analytical model based on empirical measurements. For an in-depth analysis, the CVIM has been integrated in a vehicle traffic simulator to produce CVIM-complaint data streams [...] amount of data produced within each network cell. As a result, a new car-to-cloud communication traffic model has been derived, which quantifies the data rate of aggregated car-to-cloud data producible [...] Information Model (CVIM) in combination with a cross-industry, cloud-based big data marketplace. Thereby, vehicle sensor data can be leveraged for the design of entirely new services even beyond traffic-related …

Power Consumption Analysis of NB-IoT and eMTC in Challenging Smart City Environments

techniques as well as repetitions to extend the communication range, the analysis reveals a different performance in the context of data size, rate and coupling loss. While eMTC comes with a 4% better battery [...] the 5G IoT requirements. In this paper, the performance of NB-IoT and eMTC is evaluated. Therefore, data rate, power consumption, latency and spectral efficiency are examined in different coverage conditions [...] battery lifetime raises to 18% better performance in 164 dB coupling loss scenarios. The overall analysis shows that in coverage areas with a coupling loss of 155 dB or less, eMTC performs better, but requires …
